The United Arab Emirates has told the UN Security Council a “state actor” was most likely behind attacks on four tankers off its coast.
The 12 May attacks bore the hallmarks of a “sophisticated and co-ordinated operation”, according to its report.
The UAE did not say who it thought was behind the attacks, which also targeted vessels from Saudi Arabia and Norway.
The US has accused Iran of being behind the attacks but Tehran denies this and has called for an investigation.
The attacks took place within UAE territorial waters east of the emirate of Fujairah, just outside the strategically vital Strait of Hormuz, in what the UAE called a “sabotage attack”.
They exacerbated long-standing tensions between Iran, and the US and its allies in the Gulf.
